    Which one of the following compounds liberate \[\text{C}{{\text{O}}_{\text{2}}}\] from aqueous \[\text{NaHC}{{\text{O}}_{3}}\]?

    A)  Anilinium chloride          

    B)  \[CHC{{l}_{3}}\]

    C)  \[CC{{l}_{4}}\]                                 

    D)  \[C{{H}_{3}}Cl\]

    Correct Answer: A

    Solution :

                     Anilinium chloride when treated with strong bases like \[\text{NaOH}\] or \[\text{NaHC}{{\text{O}}_{\text{3}}}\text{,}\] amines are obtained and \[\text{C}{{\text{O}}_{2}}\]gas is evolved. \[\underset{\text{Anilinium}\,\,\text{chloride}}{\mathop{{{C}_{6}}{{H}_{5}}NH_{3}^{+}C{{l}^{-}}}}\,+NaHC{{O}_{3}}\xrightarrow{{}}\]\[{{C}_{6}}{{H}_{5}}N{{H}_{2}}+NaCl+{{H}_{2}}O+C{{O}_{2}}\uparrow \]
